witz - handler with variable parameter [message #54318] Tue, 23 June 2020 02:31 Go to next message

Say I have a handler

SKYLARK(Test,"test/**")
{
	DUMP(http.GetParamCount());
	http<<"number of param :"<<http.GetParamCount();
}


And in the witz, I want to use it with a parameter called 'p'
<a url=$Test($p,3,5,7)>A link</a>


Suppose the parameter "p" has been correctly passed to the witz before calling renderResults.

Above won't work. The generated url is 'test//3/5/7' with $p treated as undefined. Did I do anything wrong?

Thanks for your help!

I figured it out by accident. Just remove the '$' before p will fix the problem.

witz should read
<a url=$Test(p,3,5,7)>A link</a>
